Depends on why they become extinct. If it is due to excessively polluted water, the impact includes things like greater disease threats and increased malnutrition.
Mind you it would take a lot to completely extinguish all amphibia, and we'd likely be suffering ill effects long before they all croaked. |

| Well currently amphibians are threatened by habitat destruction, pollution and also a fungal disease. |

What would it theoretically be if amphibians went extinct.
Would not all of animal groups go down because of loss of one of pieces in food chain and in ecosystem?
Theoretically of course |

Not all species are keystones, many ecosystems can adapt quite well to the loss of one member, especially if the role is filled by an invading species.
Also, it isn't envirohype, increased rates of amphibian extinction have been obvserved for several years now. It's partly due to climate change, but also to just plain oldfashioned polution.
Edit: The loss of wetlands has contributed a lot also. |

on the other hand, not all amphibians are endangered - some even do the endangering :

LOL, yeh, but they are the cause of the mass extinction in Australia.
But, the question, if it is possible that only amphibians are treathened... That's bullcrap! ALL species are treathened when the envirement changes. Including humans. We are not only wasting the world for the animals, but mostly for us.
Some are thriving though. Like Seagulls, Worms, Ants, Tilapia etc. Who was thinking about roaches, well. They are not that resiliant. And rats can't survive if it is above 43 degrees. (mainly because of suffication)
Still... amphibians are strange creatures. I had some in my aquarium. but they all died to soon, so i bet they are all dying

there's 2 possible responses
1. you don't know why + you try to find out why it died
2. you do know + you run like hell!

Well, if the environment changes to fast, a lot will die. We are only damaging our own chances for survival, if at all. Many more species have died out before us than we could ever kill off. After we're gone (having been one of such species), nature will carry on regardless.

Why don't you provide a countering argument rather than throwing out ad hominems. You seem to be saying that humans have no effect on the environment, that no species are endangered. Which is absolute nonsense, and when species start to be endangered it can sometimes be a sign of potential danger to humans. In Ontario a small town near a chemical plant was experiencing decreased birth rates for a long time, also almost no boys were being born. Some ecologist working in the lake nearby noted a similar pattern with the ducks in the lake, except the ducks were almost completely all female now. Turns out outrageous hormone levels in the lake had been causing the problem, and it was discovered because of concerns over falling duck populations.
Edit: After poking around turns out it was a creek  This was all from memory, but I got the gist of it right. I couldn't find the article about the ducks, but this one mentions the clear effect pollution has had on people in that town.
